[Urachal cyst. A case report and review of the literature]

The pathology of urachal disease is rarely seen. This article refers to a case of urachal cyst in a twenty-five-year-old male. In order to discuss the pathogenic, clinical and therapeutic aspects of this rare pathology, it is necessary to carry out a complete revision of the literature. Diagnosis is helped by ultrasound and CT scan of the lower abdomen, while fistulography is necessary when there is cutaneous drainage. The treatment consists of surgical approach which includes complete en-bloc excision of the cyst together with possible urachal residue. Such treatment is indispensable in order to avoid acute infection and/or malignant degeneration, frequent complications which are very serious.
